FRONT CASTER WHEEL INTERFERENCE CHECK
NOTICE
■
Do not operate tractor and mower until this interference check
has been performed. If you change tractors, you must perform the check
for that mounting.
10 Operation
Figure 8
. Front Caster Wheel Interference Check
Perform this check with all of the spacers above caster wheel arm. This will
place caster wheels in their highest position and provide lowest cutting height
for mower.
1.
Raise mower with tractor hydraulics to 406 mm at dimension C or
maximum height of tractor lift, whichever is less.
2.
Pivot both front caster wheels forward and check that there is clearance
between caster wheels and tractor tires.
3.
If there is interference adjust mower hitch arm (E) as shown in Figure 7.
NOTE: If interference continues, see tractor operator's manual and adjust trac-
tor wheels to narrower spacing.
FRONT ROLLER (OPTIONAL)
The caster wheels and side skids effectively reduce scalping in most cases.
However, you may encounter areas where the caster wheels and/or side skids
drop into depressions and allow center of the mower to contact ground and
scalp. An optional front roller may be installed to minimize scalping. See page
23.
OPERATING TECHNIQUE

Stop power unit and implement immediately upon striking an
obstruction. Dismount power unit, using proper procedure. Inspect and
repair any damage before resuming operation.
Power for operating mower is supplied by tractor PTO. Operate PTO at 540
rpm. Know how to stop tractor and mower quickly in an emergency.
If mower becomes plugged causing belt to slip for over two seconds follow
these steps:
1.
Maneuver equipment into a previously cut area and allow mower to clear
accumulated material.
2.
Continue running at least two minutes, allowing pulleys to cool. Stopping
the mower in contact with a very hot pulley will bake and ruin belt.
Proper ground speed will depend upon the terrain, the height, and type and
density of material to be cut.
Normally, ground speed will range from 5 Km to 8 Km. Tall dense material
should be cut at a low speed; thin medium-height material can be cut at a faster
ground speed.
Always operate tractor PTO at 540 rpm to maintain proper blade speed and
produce a clean cut.
Under certain conditions, tractor tires may roll some grass down and prevent it
from being cut at the same height as the surrounding area. When this occurs,
reduce your ground speed, but maintain PTO at 540 rpm. The lower ground
speed will permit grass to partially rebound.
In general, lower cutting heights give a more even cut and leave less tire
tracks. However, it is better to cut grass frequently rather than too short. Short
grass deteriorates rapidly in hot weather and invites weed growth during grow-
ing seasons. Follow local recommendations for the suitable cutting height in
your area.
